TBI is a wide spectrum of conditions akin to "trauma" in psychological terms.

I skimmed the article, but I didn't see any specific medical terms used. The reason I am curious is because I do not think that mTBI like concussions cause brain swelling since the injury is more of a functional injury than a structural injury.

I like to play ice hockey as an adult, and I try to do everything reasonably possible to protect my brain from vulcanized rubber disks flying at my head at 0 < x 100 mph. Perhaps I will add some fish oil back into my diet. I already uses Lion's Mane, but I am not sure if it truly does anything, but I love the taste of the product I use, so I will continue to use it regardless. Not sure if I have ever had a "real" concussion, but definitely some ringers.

I don't understand. "Trauma" was fairly well defined in physical terms: see Trauma Centers specializing in accident/crime victims.

Psychological "trauma" is only by analogy, and not classical "trauma", and the term is rapidly undergoing its own expansion, to a point where high prices at the grocery store can "traumatize" a sane adult with a social media account.

Well, in concussions I thought it was always odd because the literal Greek word means "wound." Concussions wound, and I am not a medical professional, cell metabolism in the brain, or something like that? Basically, concussions are functional injuries and not structural. I am of the belief that many people think trauma has to be a physical injury; however trauma is anything that injures, if I am not mistaken.

I see what you mean, but I am not sure it's restricted to that term or not (outside of psychology and slang).

------ Edit:

Though, I asked ChatGPT for the hell of it. It says that concussions are mTBI because the "Trauma" part describes the action in which a concussion is acquired. -- external force making contact with the head.

So, I guess I am wrong lol. I thought trauma had to cause physical damage and not necessarily be by physical means.

> and the term is rapidly undergoing its own expansion

No one ever said English was a beautiful language. Especially in its vernacular. Nevertheless, I find such uses of "traumatize" to be traumatizing.

Sorry, this was just a quick search, I first heard about this from Dr. Barry Sears, and he had several accounts of miraculous recovery with massive doses of fish oil (20g+)
